Brain Food....

Updated: Mar 5

There is boundless information these days on the importance of eating a balanced diet in order to nourish the body right? Well, that's all well and good, however, when was the last time you stopped to consider how important the proper nutrients are for the control center of our body. You know, the one that keeps us alive and is responsible for our thoughts, feelings, memory and concentration? It's even hard at work when we are asleep.

Nutritional psychiatry (aka Mental Health Nutrition) is a growing field that looks at the scientific evidence regarding nutritional interventions and mental health. For example, inflammation in the brain is thought to be a major cause of mental health illness which comes about after a long period of poor diet. So, what foods are best for keeping our brains well nourished? Let's dive in:

Fatty Fish

Particularly those that contain lots of omega-3 fatty acids such as salmon (especially wild caught), trout, sardines, mackerel and herring.

Why? Because approximately 60% of our brain is made of fat, and half of that is omega-3(2). Omega-3 is used by our brain to build brain and nerve cells and it is vital for our learning and memory (2,3). Not getting enough Omega-3 has been linked to depression (4).


Beautifully coloured berries - strawberries blackberries, blueberries, blackcurrants and mulberries are rich in antioxidant and anti-inflammatory effects which help our memory as we age, improve brain cell communication, and reduce depressive symptoms and (5, 6).

Nuts & Seeds

Nuts are full of omega-3 fatty acids, oxidants such as vitamin E. However, the key to eating nuts for brain health is in choosing those with specific benefits. The nut who wins the prize for the highest amount of omega -3 is the walnut. Walnuts also win for their antioxidant and anti-inflammatory properties (7). Almonds, hazelnuts and sunflower seeds win for the highest amount of vitamin E (an antioxidant), important for increased cognitive performance, reduced cognitive decline and Alzheimer's disease (7).

Tea & Coffee

Caffeine blocks boots alertness, increases capacity for processing information, reduce risk of cognitive decline, stroke, Parkinson's disease and Alzheimer's disease (8, 9, 10). However, there are some individuals who may not be able to consume caffeine or need to be careful of its consumption due to the affects it has on sleep and anxiety symptoms.


These are a great source of the good unsaturated (monounsaturated) fat which improves blood flow and reduce blood pressure (11). They are high in tyrosine, a precursor to the brain chemical dopamine that keep us motivated and focused (12).


Greens reduce oxidative stress and lower risk of neurodegenerative disease. All greens are good, however, those that are jammed with nutrients include, Broccoli, brussels sprouts, kale, spinach, romaine, arugula, collard greens and Swiss chard (13).

Dark Chocolate

Containing cocoa/cacao that contains an antioxidant - good for combating oxidative stress in the brain and contributing to protecting us from age-related cognitive decline and brain diseases. Cocoa/cacao has been found to encourage neuron and blood vessel growth in memory and learning parts of the brain as well as stimulating blood flow to the brain (14).

Garlic, Onions, Chives, Leeks, Shallots......

Used for thousands of years for a reason! Garlic contains tons of antioxidant and anti-inflammatory properties, and has been found to protect the brain against disease and age-related difficulties, reduce blood pressure (15)

We may not have control over some things, however, lets take back the control that we can.
